POLISHING OR ABRADING DEVICE.

SPECIFICATION forming part of Letters Patent No. 631,690, dated August22, 1899. Application filed November 14, 1898- Serial No. 696,366. (N'omodel.)

To all whom itv may concern.-

Be it known that I, J osnrn S. BAUM, acitizen of the United States,residing at the city of St. Louis, in the State of Missouri, haveinvented certain new and useful Improvements in Polishing or AbradingDevices, of

- which the following is a full, clear, and exact description, referencebeinghad to the accompanying drawings, forming part of thisspecification.

My invention relates to an electrical handmotor device for polishingwindow or other glass, stone, wood, metal, or other materials, or forabrading or roughening materials of any description.

Brieflystated, the invention consists in an electrical motor with asuitable handle applied thereto and a polishing or abrading slide havingconnection with the armatureshaft of the motor and arranged to bereciprocated in the operation of said shaft.

My invention consists in features of novelty hereinafter fullydescribed, and pointed out in the claims.

Figure I is a front elevation of the device. Fig. II is a sideelevation. Fig. III is a perspective view of the slide, its supports,and armature-shaft connection.

1 designates the handle of the device, on which is mounted a pair ofmagnets 2, that are adapted to be connected with a suitable supply ofelectric energy. In connection with the magnets 2 isa motor 3, having anarmature-shaft 4.

5 designates a shackle secured to the handle 1 and provided with aprojecting arm 6. On the arm 6 is a cross-piece 7, on which a pair ofguides 8 are mounted. 9 designates the polishing or abrading slide, thatis reciprocally mount-ed upon said guides 8, so as to travel to and froon said guides. I have shown the slide connected to the guides by clips10, which form boxes that travel on said guides.

On the forward end of the armature-shaft 4: is a crank 11, that isconnected to the slide 9 through means of alink 12, one end of whichlink connects with the said crank, while the other end is pivotallyjoined to the slide 9.

The slide 9 may be of any material of a suitable nature in the use ofwhich the object sought to be attained may be acccmplished. Forinstance, if it is desired to polish glass,

wood, or other materials having hard surfaces a cloth facing may beapplied to the slide, or if it is desired to abrade or roughen asurfacea sheet of sanded material might be used as a facing for the slide.Again, the slide might be entirely of some polishing or abradingmaterial of a suitable nature. I wish it understood that I do notconfine myself to the use of any particular form of slide or facing thatmay be applied thereto.

In the practical use of this device the electric motor thereof isconnected with a suitable source of electricity, the energy of whichcauses the operation of the motor and the motion of the armature'shaftto be transmitted to the slide 9 through the crank 11 and link 12,whereby the slide is caused to be rapidly reciprocally moved on theguides -8. The slide 9 is then held in contact with the surface to bepolished or abraded. The slide, moving rapidly in its action, enablesthe work of polishing or abrading to be rapidly accomplished while thedevice is moved rapidly over the surface being acted upon,

I claim as my invention- '1. In a device of the character described, thecombination of an electrical motor, a pair of magnets, a handle, ashackle mounted on said handle, a cross-piece carried by said shackle,guides mounted on said cross-piece, a reciprocating slide movablymounted on said guides, a crank carried by the armatureshaft of themotor, and a link forming aconnection between said crank and said slide,substantially as described.

2. The combination of the handle, the magnets secured to the handle, theelectric motor, having an armature-shaft and supported by the magnets,the shackle secured to the handle, the cross-piece provided withguiderods, the arm whereby the cross-piece is connected with theshackle, the reciprocating slide having clips whereby it is mounted onthe guide-rods, the crank secured to the armature-shaft, and the linkwhereby the crank is connected with the reciprocating slide;substantially as described.
